# POST /api/bulk/articles changes: the unversioned path now serves API v4, not backwards compatible

Calls to POST /api/bulk/articles on DOAJ API stopped working on July 18, 2024.

On July 18, 2024, the unversioned API path changed to serve API v4 instead of older versions. This update affected POST /api/bulk/articles, which is not backwards compatible. Following this change, calls using older formats fail.

## What to use instead

Send bulk article uploads in the v4 format to POST /api/v4/bulk/articles. Note that v1 to v3 no longer accept bulk uploads.
